How can you minimise drag on a rocket ship
WebYou can assume a “standard day” where the air density is 0.00237 slug/ft3. You will also need to accurately measure the velocity of the airflow in the tunnel. The reference area is the area of the body tube when viewed from the end. Once you have measured the drag you have everything you need to calculate the drag coefficient. Web13 de mai. de 2024 · With the positive vertical coordinate denoted by y, the net vertical force Fnet acting on the rocket is given by: Fnet = -W -D Because the weight of the object is a constant, we can use the simple form of Newton's second law to solve for the vertical acceleration: Fnet = m a = -W - D m a = - (m * g) - (.5 * Cd * r * A * v^2)

WebAs long as you have useable energy in your ship, you can use it to accelerate indefinitely your propellant in the opposite direction you want to accelerate; this is how rockets work. The propellant is basically something that carries away linear momentum in one direction so that the ship can gain momentum in the opposite direction.
WebReach over and pick up the cup. In doing so, you unbalance the forces on the cup. The weight you feel is the force of gravity acting on the mass of the cup. To move the cup upward, you have to exert a force greater than the force of gravity. If you hold the cup steady, the force of gravity and the muscle force you are exerting are in balance.
